Category Archives: Semantic Search in ONEMercury

It is essential that we compare our proposed methods against a true baseline (an existing, well known method). I have selected two methods from two papers (listed below), and is currently in the process of selecting the one to be implemented. Krestel, R., Fankhauser, P., & Nejdl, W. (2009). Latent Continue reading Week 9 Report→

This week, I have been working on writing a paper which will be submitted to LinkedScience 2012 (LISC2012), co-located with 11th International Semantic Web Conference (ISWC2012) http://linkedscience.org/events/lisc2012/. The title of the paper is “ONEMercury: Towards Automatic Annotation of Environmental Science Metadata.” The content in the paper basically summarizes what I have done Continue reading Week 8 Report→

I have put together a list of literature reviews the tools that I am using. Please see the attached: https://www.dropbox.com/s/mwk6xtdaga50pod/Literature%20Review%20Round%202.docx I am doing the experiment on the topic model based approach. The experiment takes relatively longer time than the TF-IDF — Training 300 topics with 1000 iterations could take a Continue reading Week 07 Report→

This week I was working on the implementation of the second method: the topic model based. The implementation took longer than I thought because I switched the LDA topic modeling tool from LingPipe to Standford LDA tool,due to the portability, and hence all the APIs need to be changed. I Continue reading Week 06 report→

I have made slides for this week’s report on the progress. The agenda includes: – More examples of TF-IDF results (all archives, both cross-recommendation and self-recommendation) – Precise algorithm of the Topic Model based approach. The slides can be found here: https://www.dropbox.com/s/lqrlbrcawxmzsxa/Week05.pptx The (complete) sample TFIDF results can be found Continue reading Week 05 Report→
